Name
catanh
Synopsis
Calculates the inverse hyperbolic tangent of a complex number
#include <complex.h> double complexcatanh
( double complexz
); float complexcatanhf
( float complexz
); long double complexcatanhl
( double long complexz
);
The catanh()
functions
return the number whose hyperbolic tangent is equal to their
argument z
. The imaginary part of the
return value is in the interval [-π/2 × i, π/2 × i].
Example
See the example for catan()
in this
chapter.
